Re: 2-Speed Shooter Gearbox

Our shooter reaches full operating speed in 0.6 second (due to good mechanical design coupled with software control), but we slowed it to ~ 2.0 seconds to reduce the stress on the mechanical system (to reduce the stress on our M.E. really).
I can't imagine needing to take less time than 0.6 sec. to come up to speed unless you only turn it on to fire. Not much energy gets burned simply maintaining speed though.

We use a single mini-bike motor, 3 gears, 4 pulleys and 2 timing belts, so a shifting transmission and piston would add weight.
